Final answer:
The energy of one photon from a laser pointer with a frequency of 5.64 x 10^14 s^-1 is 3.740 x 10^-19 Joules.
Step-by-step explanation:
The energy (E) of a photon can be calculated using the formula E = hf, where h is Planck's constant (6.626 x 10^-34 J·s) and f is the frequency of the photon. For a commonly used laser pointer with a frequency of 5.64 x 10^14 s^-1, the energy of one photon is:
E = (6.626 x 10^-34 J·s) * (5.64 x 10^14 s^-1) = 3.740 x 10^-19 J.
The energy of one photon of this light is 3.740 x 10^-19 Joules.
